In the back- illuminated sensor the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency the more efficient the sensor is at converting photons to electrons and hence the more sensitive the sensor is to capturing an image of something

different performance. These readout modes are currently supported in the ASCOM, SharpCap and N.I.N.A.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhotographic DSO Mode (Mode #0)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis mode is suitable for most DSO imaging situations. Since there is a drop in the noise between Gain 25 and Gain 26 (unity gain), we recommend it as default gain setting; however, gain0 is also good enough for a 16-bit sensor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Gain Mode  (Mode #1)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e This mode is something like double native iso of some new digital cameras, whose danamic range can greatly incerase at the vary high iso value, like iso800, iso3200, etc. The high gain mode provide such improvement for QHYCCD 16bit cameras. We recommend you choose this mode when you have to capture at high gain, for example, a vary dark object.\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ePlease note the switch point of HGC\/LGC of QHY600\/268\/461 is 56.

Nevertheless, QHYCCD has implemented a unique approach to achieve a full well capacity higher than 51ke- through innovative user controllable read mode settings. In Extended Fullwell Mode, the QHY600 can achieve an extremely large full-well charge value of nearly 80ke- and the QHY268 can achieve nearly 75ke-. Greater full-well capacity provides greater dynamic range and large variations in magnitude of brightness are less likely to saturate. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2CMS Modes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExtended Fullwell Mode-2CMS (Mode#3)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhotographic DSO Mode-2CMS (Mode#4)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Gain Mode-2CMS (Mode#5)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBased on the three basic modes above, 2CMS mode can greatly reduce readout noise by secondary sampling while keeping the same full well value and system gain.

In the back- illuminated sensor the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency the more efficient the sensor is at converting photons to electrons and hence the more sensitive the sensor is to capturing an image of something

different performance. These readout modes are currently supported in the ASCOM, SharpCap and N.I.N.A.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhotographic DSO Mode (Mode #0)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis mode is suitable for most DSO imaging situations. Since there is a drop in the noise between Gain 25 and Gain 26 (unity gain), we recommend it as default gain setting; however, gain0 is also good enough for a 16-bit sensor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Gain Mode  (Mode #1)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e This mode is something like double native iso of some new digital cameras, whose danamic range can greatly incerase at the vary high iso value, like iso800, iso3200, etc. The high gain mode provide such improvement for QHYCCD 16bit cameras. We recommend you choose this mode when you have to capture at high gain, for example, a vary dark object.\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ePlease note the switch point of HGC\/LGC of QHY600\/268\/461 is 56.

Nevertheless, QHYCCD has implemented a unique approach to achieve a full well capacity higher than 51ke- through innovative user controllable read mode settings. In Extended Fullwell Mode, the QHY600 can achieve an extremely large full-well charge value of nearly 80ke- and the QHY268 can achieve nearly 75ke-. Greater full-well capacity provides greater dynamic range and large variations in magnitude of brightness are less likely to saturate. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2CMS Modes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExtended Fullwell Mode-2CMS (Mode#3)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhotographic DSO Mode-2CMS (Mode#4)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Gain Mode-2CMS (Mode#5)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBased on the three basic modes above, 2CMS mode can greatly reduce readout noise by secondary sampling while keeping the same full well value and system gain.

This is particularly helpful for sensors with small pixels. In a typical front-illuminated sensor, photons from the target entering the photosensitive layer of the sensor must first pass through the metal wiring that is embedded just above the photosensitive layer. The wiring structure reflects some of the photons and reduces the efficiency of the sensor.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"color: rgb(30, 30, 30); font-size: 14px; box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; border: 0px; outline: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; line-height: inherit; vertical-align: baseline; transition: all 0.3s ease 0s;\"\u003e\u003cspan style=\"font-family: Arial;\"\u003eIn the back- illuminated sensor the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency the more efficient the sensor is at converting photons to electrons and hence the more sensitive the sensor is to capturing an image of something dim.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"color: rgb(30, 30, 30);

In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency the more efficient the sensor is at converting photons to electrons and hence the more sensitive the sensor is to capturing an image of something dim.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"color: rgb(30, 30, 30);
